Electronic transaction apparatus and computer readable storage medium on which is recorded control program for executing format conversion in electronic transaction

Abstract

A relevance information setting unit imparts the same relevance code to related elements in a standard message to indicate a relevance. A mapping processing unit displays a standard message and a local message side by side on a display and while referring to the relevance codes imparted to the standard elements, defines link relations with local elements on the display to create a conversion table for use in a message format conversion in a conversion unit. A link line appears when a standard element and a local element are selected to be linked.

What is claimed is: 
     
       1. An electronic transaction apparatus comprising: a conversion unit for performing a format conversion between a local transaction message generated by a user application in accordance with a local format proper to the user and a standard transaction message in conformity with a standard format transmitted and received through a network;   a relevance information setting unit for imparting the same relevance information to related items in said standard transaction message to indicate a relevance; and   a mapping processing unit which displays side by side said standard transaction message having said relevance information imparted thereto and said local transaction message on the same display, and while referring to relevance information imparted to the items of said standard transaction message, defines on the display link relations with the items of said local transaction message to register them into a conversion table for use in said translator format conversion.   
     
     
       2. An electronic transaction apparatus according to claim 1, wherein said mapping processing unit displays side by side an item structure of said standard transaction message and an item structure of said local transaction message on the display, and upon the selection for linking of an item of said local transaction message corresponding to an item of said standard transaction message, displays a link line between the two items.   
     
     
       3. An electronic transaction apparatus according to claim 2, wherein upon a selection for linking on the screen an item of said local transaction message corresponding to an item of said standard transaction message, said mapping processing unit performs an identification display such as a flicker and an inverse display of other items having the same relevance code as that of the linked items.   
     
     
       4. An electronic transaction apparatus according to claim 2, wherein upon a selection for linking on the display of an item of said local transaction message corresponding to an item of said standard transaction message, said mapping processing unit checks matching of the two items, and if they match each other, displays a link line, but if they are mismatched, inhibits the setting of the link. 
     
     
       5. An electronic transaction apparatus according to claim 4, wherein said mapping processing unit checks matching in attribute of an item of said standard transaction message and an item of said local transaction message, displays a link line if the two items coincide in attribute with each other, and inhibits the setting of link if they are not coincident in attribute with each other. 
     
     
       6. An electronic transaction apparatus according to claim 2, wherein in case a reselection has been made of an item of said standard transaction message displayed on the display after having once created and registered said conversion table, said mapping processing unit displays a link line between said standard transaction message item and said local transaction message item corresponding thereto on the basis of the link information in said conversion table. 
     
     
       7. An electronic transaction apparatus according to claim 4, wherein upon a registration into said conversion table after link through the selection on the display of an item of said local transaction message corresponding to an item of said standard transaction message, said mapping processing unit makes a check to see if there is any element which has not yet been input, and if any, instructs the user to perform the input operation. 
     
     
       8. An electronic transaction apparatus according to claim 2, wherein in case a reselection has been made of items through a designation of a range of a plurality of items of said standard transaction message after the creation said conversion table, said mapping processing unit displays a plurality of link lines between said items of said standard transaction message and items of said local transaction message corresponding thereto on the basis of link information of said items contained within said range designated in said conversion table. 
     
     
       9. An electronic transaction apparatus according to claim 8, wherein upon a contraction display of an item structure of said standard transaction message and an item structure of said local transaction message, said mapping processing unit groups by a plurality of items and merges for display said relevance information and link lines on group-to-group basis. 
     
     
       10. An electronic transaction apparatus according to claim 2, wherein upon a display of an item structure of said standard transaction message and an item structure of said local transaction message, said mapping processing unit displays items of each message at a reduced scale so as to allow the user to verify related items over the entirety of said messages. 
     
     
       11. An electronic transaction apparatus according to claim 10, wherein upon a selection of grouped message items, said mapping processing unit performs a detailed display of a plurality of items constituting said selected group. 
     
     
       12. An electronic transaction apparatus according to claim 1, further comprising: a system variable table in which are registered relations between items constituting said standard transaction message and system variables to which predetermined system values are assigned; and   a system variable setting unit which upon a link of items of said standard transaction message registered into said system variable table by said mapping processing unit with items of said local message, assigns system variables registered in said system variable table to said items of said standard transaction message to register them into said conversion table, wherein when a format conversion is carried out by said conversion unit, corresponding system values are assigned to said system variables for the delivery to the conversion object.   
     
     
       13. A computer readable storage medium in which is recorded a control program for executing a format conversion on an electronic transaction, comprising: a relevance information setting module for imparting the same relevance information to a plurality of related elements in a standard message to indicate a relevance,   a mapping module which displays side by side on the same display said standard transaction message having said relevance information imparted thereto and said electronic local messages generated by a user application in accordance with a user proper local format, and while referring to said relevance information imparted to said related items in said standard transaction message, defines on the screen link relations with items of said local transaction message to create a conversion table, and   a conversion module for performing a format conversion in accordance with said conversion table between said local transaction message provided by said user application and said standard message in conformity with t he standard format transmitted and received through a network.   
     
     
       14. A storage medium according to claim 13, wherein said mapping module displays side by side an item structure of said standard transaction message and an item structure of said local transaction message on the display, and upon the selection for linking of an item of said local transaction message corresponding to an item of said standard transaction message, displays a link line between the two items.
